Beast-Warrior (Japanese: 獣（じゅう）戦（せん）士（し）) is a Type of monster that usually resembles anthropomorphic animals or other half-man, half-animal creatures such as centaurs. Their effects generally apply after destroying a monster, and help them destroy monsters easier. Many of their effects also deal with Normal Monsters. However, a lot of their effects tend to give an advantage during battle, like "Exarion Universe" and "Enraged Battle Ox".

Beast-Warrior are neitherBeast nor Warrior-Type monsters, so they are not affected by effects that specifically affect Beast or Warrior-Type monsters (though occasionally, support cards for either will also specifically include Beast-Warriors, such as "Enraged Battle Ox").
